PAPER-REEL.

SPECIFICATION forming part of Letters Patent No. 623,795, dated April 25, 1899'.

Application filed October 21, 1898. $erial1lo. 694,184. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM A. LIBERT, a citizen of the United States, and a resident of Kaukauna, in the county of. Outagamie and State of Wisconsin, have invented certain new and useful Improvements in Paper-Reels; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to insure smooth winding of a continuous paper web; and it consists in providing the driving-cylinder of a paper-reel with longitudinal peripheral ribs arranged to cause automatic tilt of the winding paper and spool alternately in opposite directions at predetermined intervals, said invention being hereinafter more particularly set forth with reference to the accompanying drawings and subsequently claimed.

Figure 1 of the drawings represents a partlysectional view of a portion of a paper-reel havingits driving-cylinder provided with longitudinal peripheral ribs in accordance with my invention; Fig. 2, a perspective view of the cylinder, and Fig. 3 a diagram of said cylinder and a roll of paper wound on a spool.

Referring by letter to the drawings, A indicates the driving-cylinder; B, the countercylinder; 0, a spool, and l) a series of tension-rollers pertaining to a paper-reel, each bearing-box for the spool being loose in a vertically-slotted standard E under a yielding pressure device. The general construction and arrangement of parts thus far described are commonly employed, a web F of paper being fed down against and between the rollers D, thence under driving-cylinder A, and up over the counter-cylinder B onto the spool O, frictional contact of said driving-cylinder with the paper serving to im- From the foregoing it will be understood that as each rib G of the driving-cylinder comes into contact with the paper windin g on spool G the latter and said paper will be tilted. Owing to the disposition of the plural ribs on the cylinder the spool and paper tilt will be alternately inopposite directions at predetermined intervals to thereby prevent creasing of said paper as it winds.

The number and arrangement of the ribs herein shown are such that there is a tilt of the spool and paper in opposite directions once to every revolution of the driving-cylinder; but the ribs maybe so multiplied and disposed on said cylinder as to obtain the desired result at more frequent intervals.

The driving-cylinder ribs being of the form herein set forth, they will have shear movement on the paper-that is to say, that the higher broader portion of each rib will be the first to actand following the tilt said rib will gradually come into full contact with said paper, the straight edge or last contact-surface of said rib being parallel to said paper in a direction transverse of the same. Now as the rib passes away from the paper the tilted end of the roll has sheer drop to horizontal position parallel with the smooth surfaces of the driving and counter cylinders. As this operation takes place the tension 011 said paper has opportunity to draw the same smooth across the roll.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is

A paper-reel-driving cylinder provided at its ends With longitudinal peripheral ribs each of which is tapered on one side and has a beveled working face gradually reduced in thickness toward the inner end, its other side being straight and at a right angle to the cylinder.

In testimony that I claim the foregoing I have hereunto set my hand, at Kaukauna, in

the county of Outagamie and State of Visconsin, in the presence of two witnesses.
